54 37 ... Gauging Coupling Fastener (After Removing and Installing Roof Module)

54 37 ... - Gauging coupling fastener (after removing and installing roof module)





Special tools required:






Important!
To prevent damaging the coupling fastener gauge, set the gauge down only in the transportation crate or on the cross beam.

The coupling fastener gauge is a highly sensitive measuring instrument which reacts even to light impacts with distortion.

The coupling fastener gauge must be checked for dimensional accuracy on a master gauge after being subjected to impact or dropped.





Note:
The coupling fastener must be gauged after each removal and installation of the roof module 54 37 130 Removing and Installing Roof Module.





Necessary preliminary tasks:
- Roof module 54 37 130 Removing and Installing Roof Module must be installed
- Align basic gauge Aligning Basic Gauge





Important!
Tape off corners of roof shell 1 and 3. Risk of damage when positioning gauge for coupling fastener and assembly.

Gauge, coupling fastener:





Note:
Coupling fastener must not be screwed into place for adjustment work (barrel screws move freely).

Slacken screw for rubber stop (1) and pull back.
Insert special tool 54 0 130 in coupling fastener.





Screw gauge for coupling fastener 54 0 131 on left and 54 0 132 right onto basic gauge with special tool 00 9 251.

Tightening torque: 6 Nm





Turn L-piece (2) under stop screw (3) of coupling fastener.

Adjust coupling fastener as follows:

Set stop screw (3) with adjusting screw (1) such that it comes up against stop (4).

- Stop screw (3) of the coupling fastener is aligned flush at stop (4)
- The L-piece (2) should ideally rest against the gauge
Bring barrel screws into contact with special tool 54 0 180 in conjunction with 00 9 450.

Tightening torque: 0.2 Nm (=20 cNm).





Installation Note:
Observe screwing sequence of coupling fastener:

Refer to Installing roof module 54 37 130 Removing and Installing Roof Module.

1. Z-direction (coupling fastener to screwing plate, rollover protection system)
2. Y-direction (coupling faster to side panel)
3. X-direction (roof frame to partition wall)
